  • Patent number: 10196553
    Abstract: A method of treating a subterranean formation comprising: forming a treatment fluid by adding a desired volume of a liquid concentrate suspension to at least a base fluid, wherein the treatment fluid comprises the liquid concentrate suspension and the base fluid, and wherein the liquid concentrate suspension comprises: (A) water; (B) an additive; and (C) a magnesium silicate clay, wherein the clay increases the viscosity of the water, wherein the liquid concentrate suspension is stable for a time period of at least 2 weeks; and introducing the treatment fluid into the subterranean formation.
    Type: Grant

  • Patent number: 9738821
    Abstract: A cement composition for use in a well that penetrates a subterranean formation comprises: a calcium aluminate cement or calcium magnesia cement; water; a fluid loss additive; and a suspending agent, wherein the suspending agent is a polymer and wherein the polymer: (A) is amphoteric; (B) has a molecular weight greater than 100,000; and (C) does not increase the fluid loss of the cement composition greater than 15% at a temperature of 145° F. (63° C.) and a pressure differential of 1,000 psi (7 MPa) compared to a cement composition consisting of the cement, the water, and the fluid loss additive. A method of cementing in a subterranean formation comprises: introducing the cement composition into the subterranean formation; and allowing the cement composition to set.

  • Patent number: 9487691
    Abstract: A method of cementing in a subterranean formation comprises: introducing a cement composition into a wellbore penetrating the subterranean formation, wherein at least a portion of the subterranean formation has a temperature less than or equal to the freezing point of an aqueous liquid, and wherein the cement composition comprises: (A) cement; (B) water; and (C) a pozzolan, wherein the cement composition has a heat of hydration of less than 50 BTU per pound; and causing or allowing the cement composition to set in the wellbore after the step of introducing. The pozzolan can have a calcium oxide concentration of less than 15% by weight of the pozzolan, and the pozzolan can have a concentration of at least 15% by weight of the cement. Gas hydrates can be present in or adjacent to a portion of the well.
